To all whom t may conce. n:

Be it known that I, BENEDETTO TAMBUR- nLLo, a citizen of the UnitedStates of America, residing at New York city, county and State of NewYork, have invented certain new and useful Improvements in Demo'untableRims for Tires, of which the followingl is a full, clear, and exactdescription.

rFhis invention relates to improvements in demountable rims formotorfvehicles, the object being to provide a rim of the demountabletype consisting of separably connected members that can be. easily takenapart for removal from or application to a tire. i

One of the objects ot my invention is to provide a rim that can beeasily yapplied to a tire and also easily removed therefrom. To

accomplish this result, I provide a rim consisting' ot' (in thisinstance) two nlelnbers arranged so'that one can be slipped into theother, and also so arranged that' the tire itself will form no hindranceto the application or removal of the rim.

I will now describe the manner of carrying out the above mentionedobjects, reterence being had `to the accompanying drawings, wherein fFigurel is a cross sectional view of a de mountable rim made inaccordance with my invention;

Fig'. 2 is a sectional fragmentary perspective view illustrating themanner of securing the rim members together;

Fig. 3 a. diagran'unatic detail view illustrating' the rim memberspositioned for assemblage; j l

Fig. 1i is a similar view illustrating the rim members assembled, butnot locked;

Fig. 5 is a side view of a wheel equipped with a 4tire and my improvedrim;

Fig. 6 is a fragmentary plan view of a modied form ot' lock `for therimniembers; and

Fig. 7 is a cross sectional view thereof.

Referring to Fig. 1, the telly of a Wheel is indicated by 6, said wheelhaving the usual folly band 7. My improved rim consists of two members Sand tl, each provided with a rim flange lllfor a straight side tire (inthis instance), although rilnalanges for a clcnclmtire may also beemployed. The rim member S consists ot the herein mentiene@ rlaaugcs l0and two annular spaced,-

apart plates 11 and 12 disposed in parallel-A ism. The annular plates l1and 12 are spaced apart to provide a. channel 13 11o receive the annularplate 14, which p from the side plate 15, which in tini ries the otherrim langel() for a tire. W 1n the channel 13, I norm lugs 16 and 1",spaced apart to receive the plate 14. plate 14 also carries lugs 18 and19, which bear against the sides of the channel 13. The lugs 1G, 17, 18and 19 form supports for the plate 111, thereby obviating the necessityof having the plate 11- contact with plates 11 and 12, as such acondition Awould be objec tio-viable, on account of the liability of thesaid plates rustingtogether. The lugs 16, 17, 18 and 19 will prevent therusting of the plates together.

To lock the rim members after they have been assembled, I place withinthe channel 13 a locking-tongue Q0, consistinp,- ot an angular member(in'this instance), having a projection 21 to enter a slot Q2 extendingfrom an opening 23, cut in trom the inner edge 24 of the plate 14. Thelocking,T connection above mentioned is in the nature oi' abayonet-joint. After the rim members have been connected, in a manner tobe describ" I secure them still further by a screw passing through plate1Q, through plate 14; and engagingr a threaded opening 26 in plate 11,.To assemble the rim members, should `they be separated, the plate 14will be placed in alinement with channel 13, the openingl .be applied;hence the rim-member 9 cannot be prematurely unlocked. The screw 25will. of course be applied before the rim is placed on the wheel, orremoved after the rim has been taken from the wheel. The side plate ascan be. seen, extends the Width of the felly 6. v

The means 'lierv astcnlnp; the rim to the vWheel consists of bolts Q9,which pass through the plate 15 and engage threaded thimhles 30 carriedby the fely 5. The

The'

thimbles are inserted into the felly 6, as can be seen in Fig. 1, andthe bolts 29 pass through the felly to engage the thimbles. Lock-Washers31 may be employed to prevent the bolts 29 from shaking loose. Myimproved'rim is easily taken apart and it will be seen that the tireitself Will in no Way interfere with the assembling or d isassembling ofthe rim, as the tire will bear upon plate 11 and not upon plate lll,which is the movable plate or the plate that is removed. i'

One of the features'of my tire is that the tire does not have to bepeeled off the rim, 'as is the case With the split rim for straight sidetires. Furthermore, a tire can be more easily applied to my improved rimthan to the above mentioned split rim, which requires tools to pry thetire on. A tire can be slipped onto plate 11 after which the plate 14:can be placed in channel 13 and easily moved into place.

To prevent the channeled rim member 8 from rusting to the felly-band 7,I provide the plate 12 with lugs 12a to spa'ce the plate 17 away fromthe band 7.

Instead of employing a screw, such as 25,

to hold the rim member 9 against premature rotation, I may employ aslidable locking 12 of the rim member.

block -2 (see Fig. 6), having projections 33 at each end thereof.V Theblock 32 Will carry pins 34 engaging slots 35 in the lower plate Afterplate 14 is caused to engage the square locking block A32", the block 32Will be moved in to cause the projections' .33 to be positioned atadjacent ends of the angular tongue 36 carried by the rim member 9,after Which said rim-member Will be held against premature rotation.`(See Fig. 6;) When the rim is placed upon the wheel, the block 32 Willbe prevented from moving out of engagement With the tongue 36. It will,of course, be understood that there will be a plurality of lockingblocks 20 in the form illustratedd in Fig. 1or a plurality of blocks32a, as in the form illustrated in Fig. 6.

Having described my invention, What I claim is 1. In a demountable rim,a' channeled member, an annular plate member to engage the same, meansWithin the channel to maintain the plate member out of contact with theWalls of the channel member, and rim Hanges carried by said members.

2. In a demountable rim,` a channeled member, an annular plate member toengage the same, means Within the channel to maintain the plate memberout of contact with the Walls of the channel member, rim

flanges'carried by said members, and locking means Within the channel ofthe channeled member to engage said plate member. Signed at New Yorkcity, N'. Y., this 11th day of April, 1919.
